Not sure where you can find the info othe than the GM sight itself. Rule of thunb used to be the trailer shouldn't weight any more than the truck your hauling it with. But with a stableizing hitch 10,000 lbs should even worry you.

Trailer is 29' and will go about 8500# wet (rated at 10,000# with 2600# of cargo carrying capacity).
Our cargo, including water and propane, will go 1000-1100#, probably not more...no toys, etc. I have the 4.10 gears with the 245's on..sometimes run 265's in the summer, so probably gears up to 3.95 or so. I have a 1000# hitch (might go to 1200# if I get this trailer).

Hey, I like all this New Mexico traffic. My spring trip is scheduled for Silver City and environs, an area to which I have never been. Looking forward to it. But want to know if I'm going to have to protect my dogs from jumping cholla plants. In any case, I'll be heading down in May...in either my present Kiwi or a new trailer. Any advice will be accepted. (BTW a test tow is impractical..I'm convinced I can handle it....I have a trailer now, not as heavy, but a good bellweather.)
